Sonlu Elemanlar Modeli Anomaliliklerinin Sıvı Depolama Tanklarının Sismik Performans Değerlendirmesine Etkisi

Fluid-structure interaction (FSI) algorithms of the finite element method (FEM) is employed to evaluate the seismic response of three dimensional (3D) atmospheric tanks containing fluid under seismic loading by taking into account sources of nonlinearity of tanks. Numerical analysis model was generated both design drawing data and point cloud data obtained from 3D Laser Scan Process. All FEA Model was analysed and evaluated by performing dynamic time-history analysis under multi-dimensional. Fluid-structure interaction (FSI) was modelled with SPH technique. 5 pairs of horizontal ground motion time history components (two horizontal components for each ground motion record orthogonal to each other and vertical ground motion) was selected complying with near fault distance and frequency content of motion. Influence of imperfection in FEM modelling was evaluated in terms of seismic failure mechanism.
